  Embodiments of the invention generally provide compositions of crystalline zeolite materials with tailored crystal habits and the methods for forming such crystalline zeolite materials. The methods for forming the crystalline zeolite materials include binding one or more zeolite growth modifiers (ZGMs) to the surface of a zeolite crystal, which results in the modification of crystal growth rates along different crystallographic directions, leading to the formation of zeolites having a tailored crystal habit. The improved properties enabled by the tailored crystal habit include a minimized crystal thickness, a shortened internal diffusion pathlength, and a greater step density as compared to a zeolite having the native crystal habit prepared by traditional processes. The tailored crystal habit provides the crystalline zeolite materials with an aspect ratio of about 4 or greater and crystal surfaces having a step density of about 25 steps/µm2 or greater.
